Member Enumeration Documentation

◆ Side

enum Ogre::Plane::Side

inherited

The "positive side" of the plane is the half space to which the plane normal points.

The "negative side" is the other half space. The flag "no side" indicates the plane itself.

Constructor & Destructor Documentation

◆ PCPlane() [1/4]

Ogre::PCPlane::PCPlane ( )

Standard constructor.

◆ PCPlane() [2/4]

Ogre::PCPlane::PCPlane ( const Plane & plane )

Alternative constructor.

◆ PCPlane() [3/4]

Ogre::PCPlane::PCPlane	(	const Vector3 &	rkNormal,
		const Vector3 &	rkPoint
	)

Alternative constructor.

◆ PCPlane() [4/4]

Ogre::PCPlane::PCPlane	(	const Vector3 &	rkPoint0,
		const Vector3 &	rkPoint1,
		const Vector3 &	rkPoint2
	)

Alternative constructor.

◆ ~PCPlane()

Ogre::PCPlane::~PCPlane ( )

Standard destructor.

Member Function Documentation

◆ setFromOgrePlane()

void Ogre::PCPlane::setFromOgrePlane ( Plane & ogrePlane )

Copy from an Ogre Plane.

◆ getPortal()

PortalBase* Ogre::PCPlane::getPortal ( )

inline

Returns the Portal that was used to create this plane.

◆ setPortal()

void Ogre::PCPlane::setPortal ( PortalBase * o )

inline

Sets the Portal that was used to create this plane.

◆ getSide() [1/3]

Side Ogre::Plane::getSide ( const Vector3 & rkPoint ) const

inlineinherited

References Ogre::Plane::NEGATIVE_SIDE, Ogre::Plane::NO_SIDE, and Ogre::Plane::POSITIVE_SIDE.

Referenced by Ogre::PlaneBoundedVolume::intersects(), and Ogre::Math::intersects().

◆ getSide() [2/3]

Side Ogre::Plane::getSide ( const AxisAlignedBox & box ) const

inlineinherited

Returns the side where the alignedBox is.

The flag BOTH_SIDE indicates an intersecting box. One corner ON the plane is sufficient to consider the box and the plane intersecting.

References Ogre::AxisAlignedBox::getCenter(), Ogre::AxisAlignedBox::getHalfSize(), Ogre::AxisAlignedBox::isInfinite(), and Ogre::AxisAlignedBox::isNull().

◆ getSide() [3/3]

Side Ogre::Plane::getSide	(	const Vector3 &	centre,
		const Vector3 &	halfSize
	)		const

inlineinherited

Returns which side of the plane that the given box lies on.

The box is defined as centre/half-size pairs for effectively.

Parameters

centre	The centre of the box.
halfSize	The half-size of the box.

Returns: POSITIVE_SIDE if the box complete lies on the "positive side" of the plane, NEGATIVE_SIDE if the box complete lies on the "negative side" of the plane, and BOTH_SIDE if the box intersects the plane.

◆ getDistance()

Real Ogre::Plane::getDistance ( const Vector3 & rkPoint ) const

inlineinherited

This is a pseudodistance.

The sign of the return value is positive if the point is on the positive side of the plane, negative if the point is on the negative side, and zero if the point is on the plane.

: The absolute value of the return value is the true distance only when the plane normal is a unit length vector.

References Ogre::Vector< dims, T >::dotProduct().

Referenced by Ogre::Sphere::intersects(), and Ogre::PlaneBoundedVolume::intersects().

◆ redefine() [1/2]

void Ogre::Plane::redefine	(	const Vector3 &	p0,
		const Vector3 &	p1,
		const Vector3 &	p2
	)

inlineinherited

Redefine this plane based on 3 points.

References Ogre::Math::calculateBasicFaceNormal(), and Ogre::Vector< dims, T >::dotProduct().

◆ redefine() [2/2]

void Ogre::Plane::redefine	(	const Vector3 &	rkNormal,
		const Vector3 &	rkPoint
	)

inlineinherited

Redefine this plane based on a normal and a point.

References Ogre::Vector< dims, T >::dotProduct().

◆ projectVector()

Vector3 Ogre::Plane::projectVector ( const Vector3 & v ) const

inlineinherited

Project a vector onto the plane.

Remarks: This gives you the element of the input vector that is perpendicular to the normal of the plane. You can get the element which is parallel to the normal of the plane by subtracting the result of this method from the original vector, since parallel + perpendicular = original.

Parameters

v	The input vector

◆ normalise()

Real Ogre::Plane::normalise ( void )

inlineinherited

Normalises the plane.

Remarks: This method normalises the plane's normal and the length scale of d is as well.

Note: This function will not crash for zero-sized vectors, but there will be no changes made to their components.

Returns: The previous length of the plane's normal.

References Ogre::Vector< dims, T >::length().

◆ operator-()

Plane Ogre::Plane::operator- ( ) const

inlineinherited

Get flipped plane, with same location but reverted orientation.

◆ operator==()

bool Ogre::Plane::operator== ( const Plane & rhs ) const

inlineinherited

Comparison operator.

References Ogre::Plane::d, and Ogre::Plane::normal.

◆ operator!=()

bool Ogre::Plane::operator!= ( const Plane & rhs ) const

inlineinherited

References Ogre::Plane::d, and Ogre::Plane::normal.
